I have 5 female chinese mantids and 3 males. All are at least 1 month past final molt. I am having a difficult time breeding them, the males show absolutely zero interest in the females. I have tried many techniques mentioned here with no luck. I have placed the males on the females back and they just crawl off. Any suggestions? All of their enclosers are kept next to each other, could the males have been desensitized to the females feramones?
